Dive Boat Safety Tips for Scuba Diving Trips Every Diver Should Know

Stay Safe. Dive Smart. Enjoy the Adventure.

Whether you’re a brand-new open water diver or a seasoned pro with hundreds of dives under your belt, dive boat safety is something that should never be taken for granted. Divers often get caught up in the excitement of the day — the gear, the marine life, the adventure ahead. But a successful dive trip starts and ends with solid safety practices on the boat.

Dive boats present an entirely different environment than shore diving. From moving ladders to slippery decks and the ever-present boat propeller, hazards are real — but with awareness, preparation, and a proactive mindset, these risks can be minimized.

Let’s break it down.

1. Before You Board: Know What to Expect

Understanding your trip helps you dive more confidently — and avoid surprises.

Before the trip, find out:

• What kind of boat you'll be on

• Sea and weather conditions

• Dive site conditions (currents, depth, visibility)

• Entry and exit methods

• Gear requirements — and whether you need to bring or rent any extra equipment

If you’re unsure whether the dive matches your experience level, don’t be afraid to ask the operator. It's okay to sit one out if it doesn’t feel right — the ocean will still be there next time!

2. Pack with Purpose: Be Gear Ready

Bringing the right gear makes your dive safer and more comfortable.

Consider bringing:

• Surface Marker Buoy (SMB)

• Sun protection (hat, rash guard, sunscreen)

• Water, snacks, and a towel

• A dry bag for valuables

• Seasickness meds (take them before boarding if needed)

• Motion-friendly footwear (no flip-flops!)

Also — double-check your dive gear before you go. A loose inflator hose or missing o-ring is a bad surprise to find once you're out at sea.

3. The Briefing: Listen Up

Before the dive, the crew will go over important info — and they’re not just filling time.

They’ll usually cover:

• Where to sit and stow gear

• How to board, gear up, and enter/exit the water

• Emergency procedures and equipment locations

• Entry/exit order and dive buddy procedures

This is the time to ask questions if you’re unsure about anything — and to keep distractions (like chatting or messing with your gear) to a minimum.

4. Watch Your Step: Deck Hazards

The deck can be unpredictable — especially when wet or cluttered with gear.

Be aware of:

• Loose hoses, tanks, and weights

• Slippery surfaces from water or sunscreen

• Boat rocking unexpectedly

Pro Tips:

• Wear secure, non-slip footwear

• Move slowly and use handrails when available

• Don’t run or jump — even if the boat is anchored

  
  

5.Ladder Safety: Take it One Step at a time

You’re done with your dive, you’re feeling great — but the dive ladder can still be dangerous.

Common hazards:

• Getting hit by a moving ladder in rough seas

• Slipping off while climbing

• Getting underneath another diver as they board

Play it safe:

• Always keep three points of contact (two hands and a foot, or two feet and a hand)

• Never carry gear up the ladder — hand it to the crew first

• Face the ladder while climbing (like a ladder, not stairs)

• Stay clear of the ladder until it's your turn to board

  
  

6. Propeller Awareness: Out of Sight, Still a Threat

Boat propellers can cause serious injury — even when the engine seems quiet.

To stay safe:

• Follow crew directions when entering or exiting the water

• Avoid swimming behind the boat

• Stay in the designated area where crew expects you to be

• Use your Surface Marker Buoy (SMB) when surfacing away from the boat

  
  

7. While Underway: Be Smart, Stay Seated

Once the boat is moving, safety matters even more.

Stay safe by:

• Staying seated while underway

• Holding on when moving around

• Watching out for gear on the floor

• Keeping hydrated and protected from sun or wind

If you start to feel seasick, head to a shaded, stable part of the boat and focus on the horizon. Let the crew know if you need help — it happens to almost everyone at some point!

8. After the Dive: Take Care of Yourself (and Your Gear)

After a dive, your job isn’t over yet.

Post-dive safety checklist:

• Hydrate, snack, and stay warm or cool off as needed

• Listen to your body — tiredness and dehydration can lead to accidents

• Watch out for signs of decompression illness (DCI): joint pain, dizziness, or shortness of breath

• Avoid hot tubs, deep massages, alcohol, and flying for at least 18–24 hours

• Stow your gear securely before heading back to shore

  
  

9. Liveaboard Travel: Safety 24/7

If you're headed on a liveaboard trip, the safety guidelines extend beyond the dive deck.

Key tips for liveaboards:

• Learn the boat’s emergency procedures — alarms, muster stations, exits

• Pack a small go-bag with essentials like your passport, medication, flashlight, and dry clothes

• Keep your bag close to your bunk in case of emergency

• Don’t store charging devices on beds or unsupervised areas — fire risk is real

• Take it slow — fatigue and dehydration are more common on multi-day dive trips

Dive Smart, Dive Often

Dive boats are your gateway to some of the most amazing dive sites in the world — but they require you to stay alert, follow instructions, and look out for yourself and your dive buddies.

Remember:

• Listen to the crew

• Respect the sea and the boat

• Know your limits

• Pack smart

• Speak up if something doesn’t feel right

A safe diver is a confident diver — and confident divers have the most fun.
